Roll forming, also spelled rollforming, is a continuous bending operation in which a long strip of sheet metal (typically coiled steel) is passed through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section profile is obtained. Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities.
Famous quotes containing the words roll and/or forming:
“Let us have a good many maples and hickories and scarlet oaks, then, I say. Blaze away! Shall that dirty roll of bunting in the gun-house be all the colors a village can display? A village is not complete, unless it have these trees to mark the season in it. They are important, like the town clock. A village that has them not will not be found to work well. It has a screw loose, an essential part is wanting.”
—Henry David Thoreau (1817–1862)
“As boys without bonds to their fathers grow older and more desperate about their masculinity, they are in danger of forming gangs in which they strut their masculinity for one another, often overdo it, and sometimes turn to displays of fierce, macho bravado and even violence.”
—Frank Pittman (20th century)
